D4701A Product details

Description

The µPD4701A is a counter for an X, Y 2-axis incremental encoder.

When a two-phase encoder signal is input for the X and Y axes, direction discrimination and computation is performed, and count data is output in 8-bit parallel form.

Features

X, Y 2-axis incremental encoder counter.
Counter input (Schmitt-triggered input) X axis: XA, XB 2-phase signal   4-multiplication count method used Y axis: YA, YB 2-phase signal .
Counters: 12-bit binary up/down counters (2 sets, X & Y) Reset value: 000H.
Count data output: 8-bit parallel latch output × 2 (including key input flag).
On-chip 3-contact-point key input buffer circuit.
CMOS.
Single +5 V power supply PIN.
